The Xcel generating station at Tacoma (alongside the D&S) is operated as a "peaking" plant, according to Xcel:

Xcel Energy
Water for plant operations comes from 18 miles upstream on Cascade Creek, where it passes through a 4,400-foot open wooden flume, one of only two wooden flumes still operating on hydro projects in the United States. Electra Lake provides 22,000-acre feet of storage for year-round operations. The plant’s powerhouse is located in Animas River Canyon and is accessible only by a narrow gauge train or track car.
Tacoma Hydro is considered a peaking plant.
